Abstract (en)
[origin: WO8504165A1] Molded construction article which is pressure-molded and wet with hydration water, having characteristics similar to those of asbestos ciment, based on an asbestos-free mixture with, in a highly compressed state, up to 30% by volume of cellulose fiber parts (F) of a diameter spectrum (DC), which are highly integrated separately to a hydration binder particle mixture (B) which is still in a wet molding state, with main distribution spectum (Do) of particulate size verifying the equation 0.9 <= DC/Do <= 1.1, which contains in the case of the participation of cement to the binder, special puzzolanic additives to provide for a constant life time quality.
